Question '03 7.3 F-350 Needs Help!

I was going 65 mph towing an empty, light, horse trailer (about 1,500 lbs).
Then the engine started to vibrate violently (heard a tapping noise), I let of the gas, and pulled to the shoulder and on the way, the engine turns off. No warning lights before incident. Had trouble pulling dipstick out--it was bent and scratched. Straightened dipstick out and no oil in crankcase. Left a trail of oil about 200 feet long. Oil coming out of front of engine, say front main seal. No other damage noted. AAA towed F-350 back to farm. Now what?

well.. hoping you didn't lock up te engine. Probably going to need a complete engine rebuild along with possibly new oil lines, hpop, front and rear oil seals... sorry about your truck

Engine will crank (I won't even try to start it). What could have happened?

your motor will turn off, when low on oil. I hardly doubt your motor is toast. Its a "feature" thats cool about low oil. If oil from the front, probably lost your lpop. Get a Melling 208 and be done ,bud.

What caused the pressure? I thought crankcases were ventilated?

Thank you, but what is an "lpop"?

What bent and scratched the dipstick (about 3" from the tip)?

low pressure oil pump. and that could have been something f***ing up inside and hitting it under high pressure

True but it is common for PCVs to get clogged. Thus resulting in no ventilation and high pressure. Happened to my ol 7.5 460
